[0044] This utility model proposes a photography-assisted mobile vehicle, which is mainly used in photography and videography auxiliary equipment.

[0045] Reference Figure 1 As shown, in this embodiment of the utility model, the photography-assisted mobile vehicle includes a vehicle body 100 and a plurality of wheel mechanisms 200 disposed on the vehicle body 100. The wheel mechanism 200 includes:

[0046] Mounting bracket 210 is connected to vehicle body 100;

[0047] The wheel frame 220 is rotatably connected to the mounting base 210;

[0048] The wheel 230 is rotatably mounted on the wheel frame 220. The wheel 230 can rotate with the wheel frame 220 relative to the mounting base 210 to be folded horizontally or unfolded vertically.

[0049] In this embodiment, the photography auxiliary mobile vehicle is a tool cart used to place and transfer photography-related accessories on the shooting site. Photography-related accessories, such as spare lenses, tripod mounts, and small fill lights, can be placed in the vehicle body 100. The mounting base 210 is connected to the vehicle body 100 via threads. The shape of the mounting base 210 can be rectangular, circular, etc. One side of the mounting base 210 is fixedly connected to the vehicle body 100, and the other side is hinged to the wheel frame 220, allowing them to rotate. The rotational connection method is selected according to actual needs; any method that allows rotation is acceptable and will not be elaborated further. The wheel 230 is rotatably mounted on the other hinged side of the wheel frame 220. The surface of the wheel 230 is provided with anti-slip texture to provide good friction. The wheel 230 is mounted on the bushing of the wheel frame 220 via bearings. For example, the mounting base 210 is designed in an "L" shape, with the inner sides of the two right-angled sides of the "L" shape connected to the side and bottom surfaces of the vehicle body 100 respectively, increasing the contact area between the mounting base 210 and the vehicle body 100 and ensuring the stability of the connection. The wheel frame 220 is U-shaped, with symmetrical bushings on both sides of the open end for mounting the rotating shaft of the wheel 230. A rotating shaft is located on the outer side of the closed end of the U-shaped wheel frame 220, and this shaft engages with a cylindrical sleeve on one right-angle side of the L-shaped mounting base 210 to achieve a rotatable connection. The wheel 230 is rotatably mounted on the wheel frame 220 and can rotate relative to the mounting base 210, allowing for horizontal folding or vertical unfolding. This allows the photography auxiliary mobile vehicle to be stored by folding the wheels 230 horizontally, significantly reducing its footprint and facilitating storage and transport; and to be unfolded vertically during use, ensuring stable movement of the mobile vehicle and meeting the dual requirements of mobility and equipment stability during photography.

[0050] Reference Figure 2 and Figure 3 As shown, in some embodiments, the wheel carrier 220 is configured to have at least one locking angle, and the wheel mechanism 200 further includes:

[0051] The locking assembly 240 is disposed on the vehicle body 100 or the mounting base 210 and located on one side of the wheel carrier 220. The locking assembly 240 is used to lock the wheel carrier 220 when the wheel carrier 220 is rotated to the locking angle.

[0052] In this embodiment, during the rotation of the wheel frame 220 around the mounting base 210, it can stop at a specific preset angle position, which serves as a locking angle, thus fixing the wheel frame 220 to the locking component 240 and stopping its rotation. Of course, there can be multiple locking angles, allowing different angles to be formed between the wheel frame 220 and the mounting base 210 to meet the needs of different usage postures while maintaining the stability of both the wheel frame 220 and the mounting base 210. The locking component 240 is installed on the side of the vehicle body 100 or the mounting base 210 facing the wheel frame 220. The locking component 240 includes a locking tongue, a locking latch, a driving device, and related connecting support structures. For example, the locking component 240 is disposed on the vehicle body 100. The locking component 240 is mechanically and manually driven, with the driving device being an elastic element 243. When the wheel frame 220 rotates to the locking angle, the spring automatically pushes the locking tongue into the locking latch on the wheel frame 220, thereby firmly fixing the wheel frame 220 and preventing it from continuing to rotate. The preset locking angle can help photographers quickly rotate the wheel 230 to a specific position, and the locking component 240 ensures stability between the wheel mechanism 200 and the vehicle body 100, preventing shaking and displacement.

[0053] Reference Figure 3 and Figure 4 As shown, in some embodiments, the wheel carrier 220 is provided with at least one locking groove 250, each locking groove 250 corresponding to a locking angle; the locking assembly 240 locks the wheel carrier 220 by forming a locking engagement with the locking groove 250 or releases the locking engagement with the locking groove 250 to release the wheel carrier 220.

[0054] In this embodiment, at least one locking groove 250 is pre-set on the wheel frame 220, and each locking groove 250 corresponds to a specific locking angle. The locking groove 250 can be a semi-circular or rectangular groove, distributed around the circumference of the wheel frame 220, so that the wheel frame 220 can be precisely aligned with the locking assembly 240 when rotated to a specific angle. For example, the wheel frame 220 is provided with a locking plate near the locking assembly 240. The locking plate is symmetrically provided with two circular lugs, the axes of which are parallel to the rotation axis of the wheel frame 220. The surface of the circular lugs is constructed with semi-circular locking grooves 250. When the wheel frame 220 rotates to the corresponding locking angle, the locking assembly 240 engages with the locking groove 250 to achieve quick locking. When unlocking, the locking assembly 240 is disengaged from the locking groove 250, and the locking assembly 240 exits from the locking groove 250. Since the position of the locking groove 250 corresponds one-to-one with the specific locking angle, the wheel frame 220 is accurately fixed at multiple locking angles. Users can select different angles to lock as needed. When the wheel frame 220 is rotated to a specific angle, the locking component 240 automatically locks through a spring or other structure without additional operation, improving portability and ease of installation.

[0055] Reference Figure 4 and Figure 5 As shown, in some embodiments, the locking component 240 includes:

[0056] Connector 241 is connected to vehicle body 100 or mounting base 210;

[0057] The locking switch 242 is slidably disposed on the connecting base 241. The locking switch 242 can be slidably inserted into the locking groove 250 to form a locking engagement with the locking groove 250 or withdrawn from the locking groove 250 to cancel the locking engagement with the locking groove 250.

[0058] The elastic element 243 is provided on the connecting seat 241 and acts on the locking switch 242. The elastic element 243 is used to provide the locking switch 242 with an elastic force to make it slide and reset.

[0059] In this embodiment, the connecting seat 241 is connected to the vehicle body 100 or the mounting seat 210. The connecting seat 241 is used to accommodate the locking switch 242 and the elastic element 243. The connecting seat 241 has a guide groove or slide rail to limit the sliding direction of the locking switch 242 and ensure that the locking switch 242 can slide stably into the locking groove 250. The locking switch 242 is used to slide into the locking groove 250 to achieve locking engagement when the rotation angle of the wheel frame 220 reaches the locking angle. The locking switch 242 can be driven by a manual button or an electronic control device, which is convenient for users to perform unlocking or locking operations. The elastic element 243 provides elastic force for the locking switch 242 to slide and reset, ensuring that the locking switch 242 automatically returns to the initial position after exiting the locking groove 250, preparing for the next locking. For example, the connecting seat 241 is U-shaped. The closed end of the U-shaped connecting seat 241 is fixed to the side of the vehicle body 100 near the wheel frame 220. The two sides of the open end of the U-shape are located inside the circular ear plate on the locking seat, and the connecting seat 241 is rotatably connected to the circular ear plate by a rotating pin. A locking switch 242 and an elastic element 243 are provided on the inner side of the U-shaped connecting seat 241.

[0060] Reference Figure 5 As shown, in some embodiments, the connector 241 is configured with a first sliding hole 244 and a second sliding hole 245, the extending direction of the second sliding hole 245 forming an angle with the extending direction of the first sliding hole 244, and the locking switch 242 includes:

[0061] The locking shaft 246 passes through the first sliding hole 244 and is slidably engaged with the first sliding hole 244. The locking shaft 246 is used to slide along the first sliding hole 244 to insert into or retract from the locking groove 250.

[0062] The sliding shaft 247 is slidably engaged with the second sliding hole 245 and is arranged parallel to the locking shaft 246;

[0063] The unlocking press 248 is respectively sleeved on the locking shaft 246 and the sliding shaft 247. When the unlocking press 248 is subjected to external force, it is used to drive the locking groove 250 to slide.

[0064] One end of the elastic element 243 is connected to the connecting seat 241, and the other end is sleeved on the locking shaft 246.

[0065] In this embodiment, a first sliding hole 244 and a second sliding hole 245 are provided on the connecting seat 241. The first sliding hole 244 is used to guide the sliding of the locking shaft 246, and its length direction is the path for the locking shaft 246 to insert into or exit the locking groove 250. The second sliding hole 245 is used for the sliding of the sliding shaft 247, and its length direction forms a specific angle with the first sliding hole 244. The locking shaft 246 passes through the first sliding hole 244 and can slide horizontally within the first sliding hole 244. The locking shaft 246 can form a locking or unlocking engagement with the locking groove 250 by sliding, ensuring precise locking. The sliding shaft 247 and the locking shaft 246 are arranged parallel to each other, forming a two-point sliding support, which improves the stability and impact resistance of the overall structure. The unlocking pressing member 248 is respectively sleeved on the locking shaft 246 and the sliding shaft 247, and when pressed by an external force, it drives the locking shaft 246 and the sliding shaft 247 to slide synchronously. When the unlocking press 248 is pressed, the sliding shaft 247 and the locking shaft 246 slide in conjunction, causing the locking shaft 246 to exit the locking groove 250, thus completing the unlocking. One end of the elastic element 243 is fixed to the connecting seat 241, and the other end is sleeved on the locking shaft 246. For example, the two sides of the open end of the "U"-shaped connecting seat 241 are symmetrically provided with a first sliding hole 244 and a second sliding hole 245. The first sliding hole 244 is horizontally arranged near the locking groove 250, and the second sliding hole 245 is near the unlocking press 248 and is horizontally inclined relative to the first sliding hole 244. When the unlocking press 248 is pressed, the sliding shaft 247 slides along the second sliding hole 245, while the locking shaft 246 slides along the first sliding hole 244. The sliding directions of the two are at a certain angle, so that the unlocking press 248 moves as a whole in a horizontally inclined downward direction.

[0066] In this embodiment, for example, when the wheel carrier 220 is locked at a certain locking angle, the initial position of the locking shaft 246 is located within the locking groove 250, at which point the wheel carrier 220 is fixed and cannot rotate. When it is necessary to rotate the wheel carrier 220 to another locking angle, the user presses the unlocking press 248, causing the unlocking press 248 to drive the sliding shaft 247 to slide along the second sliding hole 245. At the same time, the locking shaft 246 slides out of the locking groove 250 along the first sliding hole 244, thus unlocking. After the unlocking operation is completed, the user releases the unlocking press 248, and the wheel carrier 220 can rotate freely. Under the elastic force of the elastic member 243, the locking shaft 246 always abuts against the edge of the circular ear plate on the locking seat until the wheel carrier 220 rotates to another locking angle. At this point, the locking shaft 246 automatically slides into the locking groove 250, completing the locking engagement.

[0067] In this embodiment, the linkage design of the first sliding hole 244 and the second sliding hole 245 ensures that the unlocking press 248 does not move in a single direction, but moves simultaneously in the horizontal and vertical directions, effectively preventing the locking shaft 246 from jamming or being misoperated. The sliding shaft 247 is arranged parallel to the locking shaft 246, and during unlocking, the sliding shaft 247 and the locking shaft 246 form two-point support, preventing tilting or shaking that may occur when a single locking shaft 246 is unlocked, thus improving the stability of the structure.

[0068] In some embodiments, the vehicle body 100 further includes a control component, which is linked to the locking switch 242 of each wheel mechanism 200. The control component is used to drive the locking switch 242 of each wheel mechanism 200 to slide.

[0069] In this embodiment, the control component is used to achieve linkage control of the locking switches 242 of each wheel mechanism 200, and can simultaneously or separately control the locking and unlocking of the wheel mechanisms 200. The control component consists of a control handle, a linkage mechanism, etc. The control handle is used by the user and is set on the vehicle body 100. It can be a push-pull type, a rotary type, or a button type, and has the function of pushing forward to lock and pulling backward to unlock. The linkage mechanism is used to link the control handle with the locking switches 242 of each wheel mechanism 200. It can be a pull cable, a linkage rod, or a gear set for mechanical linkage to ensure that all wheel mechanisms 200 slide to lock or unlock simultaneously. When using the control component, the user pulls the control handle, and the transmission is transmitted to the locking switch 242 through the pull cable, linkage rod, or gear set, causing the locking switch 242 to disengage from the locking groove 250, thereby realizing the simultaneous sliding of the locking switches 242 of all wheel mechanisms 200, achieving one-button unlocking. This greatly improves the unlocking efficiency.

[0070] Reference Figure 2 As shown, in some embodiments, the locking angle includes a first locking angle, which the wheel carrier 220 rotates to when it is vertically unfolded; and / or,

[0071] The locking angle includes a second locking angle, and the wheel carrier 220 is folded horizontally when rotated to the second locking angle.

[0072] In this embodiment, when the wheel frame 220 rotates to the first locking angle, it is in a vertically unfolded state, used to stably support the photography assistance mobile vehicle. At this time, the angle between the first locking angle and the horizontal plane is 90°. When the wheel frame 220 rotates to the second locking angle, it is in a horizontally folded state, used for portable storage or transportation of the photography assistance mobile vehicle. At this time, the second locking angle is either 0° or 180° with the horizontal plane. Therefore, the wheel frame 220 is provided with multiple locking slots 250, each corresponding to a different locking angle. For example, the first locking slot 250 corresponds to the vertically unfolded state, and the second locking slot 250 corresponds to the horizontally folded state. The wheel frame 220 supports locking in both vertically unfolded and horizontally folded states, and can also add intermediate angle locking slots 250 as needed, making it suitable for different shooting environments and requirements, thus allowing for flexible use of the photography assistance mobile vehicle.

[0073] In some embodiments, when the wheel 230 is folded horizontally, it is within the projection range of the vehicle body 100 projected along its vertical direction.

[0074] In this embodiment, the vertical projection of the vehicle body 100 refers to the outer contour area of ​​the vehicle body 100 projected onto the horizontal plane along the vertical direction (usually the up-down direction). When the wheel 230 is folded horizontally, the wheel holder 220 can fit snugly against the vehicle body 100 and remain within the vertical projection range of the vehicle body 100, achieving compact storage and improved portability. For example, the wheel mechanism 200 is located at the bottom edge of the wheel 230 and folds inward towards the vehicle body 100, so that the wheel 230 is within the range of the vehicle body 100 when folded. This effectively reduces the space occupied by the wheel 230 and ensures that the wheel holder 220 is in a safe and fixed position, preventing movement and damage.

[0075] Reference Figure 4 As shown, in some embodiments, wheel 230 is a Mecanum wheel.

[0076] In this embodiment, the Mecanum wheel is a specially designed wheel that allows the mobile vehicle to move in all directions (omnidirectional motion) without changing the wheel's direction. The Mecanum wheel consists of a hub, angled rollers, roller bearings, and a support. The hub is the central part of the Mecanum wheel and is fixedly connected to the wheel frame 220. Multiple angled rollers (typically at a 45° angle) are evenly distributed around the outer circumference of the hub on the outer rim of the Mecanum wheel. The angled rollers on each wheel 230 are tilted at 45° to each other, allowing the vehicle body 100 to move flexibly forward, backward, left, right, diagonally, and in the direction of rotation.

[0077] Reference Figure 1As shown, in some embodiments, the vehicle body 100 includes:

[0078] First shelf 110;

[0079] The second shelf 120 is arranged vertically opposite to the first shelf 110;

[0080] The lifting mechanism 130 is located on the first storage platform 110 and connected to the second storage platform 120. The lifting mechanism 130 is used to drive the second storage platform 120 to rise or fall.

[0081] The plurality of wheel mechanisms 200 are connected to the first storage platform 110.

[0082] In this embodiment, the first platform 110 serves as a bottom platform, providing stable support for the entire vehicle body 100 and is fixedly connected to multiple wheel mechanisms 200. For example, four Mecanum wheels are used, installed at the four corners of the vehicle body 100, forming an X-shaped layout. A fixed rotating shaft, track, or groove can be provided on the first platform 110 to connect to the lifting mechanism 130. For example, the first platform 110 and the lifting mechanism 130 are rotatably connected. The lifting mechanism 130 is used to raise or lower the second platform 120, adjusting its height. The lifting mechanism 130 can employ electric lifting, hydraulic lifting, screw lifting, etc. For example, the height of the second platform 120 can be precisely adjusted through the cooperation of a screw, guide rod, and guide block. The connection between the second platform 120 and the lifting mechanism 130 can be achieved by bolt fixing or embedded slots. For example, the second platform 120 is fitted onto the guide rod of the lifting mechanism 130 via a guide block. When the second storage platform 120 is raised or lowered, the user issues a raising or lowering command via the control panel or remote control. The lifting mechanism 130 rotates via a screw, causing the second storage platform 120 to rise or fall. When the vehicle body 100 needs to be stored or transported, the second storage platform 120 can be lowered and overlapped with the first storage platform 110. At this time, the lifting mechanism 130 can rotate toward the second storage platform 120 and overlap with it, reducing the overall volume of the vehicle body 100. Simultaneously, the wheel mechanism 200 folds into the vehicle body 100, further saving space, improving the portability of the equipment, and facilitating storage and transportation.
